The seven NPN Darlington junction transistors in these arrays are ideal for driving lamps, relays or printing hammers in a variety of industrial and consumer applications. Its high breakdown voltage and internal suppression diodes ensure that inductive loads will not be a problem. The peak inrush current of up to 500 mA enables it to drive incandescent lamps. The ULx2003A with a 2.7 kΩ series input resistor is suitable for systems using 5.0 V TTL or CMOS logic.
